How this service works
Detect the language of any text input using character frequency analysis and n-gram pattern matching — returns the detected language, ISO code, confidence score, and top alternative languages so agents can route multilingual content, trigger translation workflows, and classify text without a paid NLP API.
Output
Returns the detected language (e.g. 'French'), its ISO 639 code (e.g. 'fr'), a confidence score between 0 and 1, and a ranked list of top alternative language candidates with their own scores — enough to route or filter multilingual content reliably.
Example use cases
Example prompt
“What language is this text written in, and how confident are you? — 'Bonjour, je m'appelle Marie et je travaille à Paris.'”
Technical details
Endpoint
POSThttps://netintel-production-440c.up.railway.app/lang-detect/analyzeWhen to prefer
Choose this endpoint when you need lightweight, low-cost language detection without a paid NLP platform dependency. Ideal for routing multilingual content, pre-filtering before translation, or classifying user-submitted text in pipelines where cost per call matters. The confidence score and alternative candidates make it suitable for downstream decision logic.
Side effects
- Text too short for reliable detection — low confidence score returned
- Mixed-language or code-switched text may yield low confidence or wrong top language
- Constructed or nonsense text returns low confidence with unreliable language assignment
- Empty or whitespace-only input returns a validation error
- Very short strings like single words may match multiple languages with near-equal confidence
